Abstract: A radio-resource assignment control mode for assigning radio resources for an inter-terminal direct communication to plural UEs in a same group is appropriately selected to ensure low latency and highly reliable inter-terminal direct communications in the same group. A radio-resource assignment control mode for assigning the radio resources for the inter-terminal direct communication of the plural UEs 20 belonging to a group can be selected from a first mode in which a base station assigns radio resources for inter-terminal direct communication and a second mode in which any one of plural UEs assigns radio resources for inter-terminal direct communication.

Abstract: A relay device is provided that is provided on a first network hierarchy level and relays communications via a network hierarchy level higher than the first level, between a plurality of nodes subordinate to the relay device and a sales broker website, and includes: an application storage unit storing a sales broker application; and an application execution unit executing the sales broker application to cause the relay device to function as: an order data reception unit receiving order data including a plurality of contents; a first order data transmission unit transmitting the order data to the sales broker website; and a second order data transmission unit transmitting, when an order receiver node receiving an order for the product is any of the plurality of nodes, at least a part of the plurality of contents to the order receiver node without involving a level higher than the first level.

Abstract: A system is provided that includes: a first relay device provided on a first network hierarchy level; and a second relay device provided on a second network hierarchy level higher than the first network hierarchy level. The first relay device includes: a first information reception unit that receives target object information about a target object, transmitted by a radio tag attached to the target object in accordance with a predetermined timing; a first information storage unit that stores the target object information received by the first information reception unit; a first change determination unit that determines whether there has been a change in a status of the target object, based on a status of reception of the target object information; and a first information transmission unit that transmits the target object information to the second relay device, when the first change determination unit determines that there has been the change.

Abstract: A multibeam scanning apparatus includes a polygon mirror provided between laser beam generation sources and a photosensitive drum of a target, for deflecting laser beams emitted from the laser beam generation sources to scan the photosensitive drum, galvanomirrors provided between the polygon mirror and each of the laser beam generation sources, for allowing a radiating position of each of the laser beams to move on the photosensitive drum, a sensor located in a downstream position of the polygon mirror and optically in conjugation with the photosensitive drum, for sensing the radiating positions of the laser beams on the photosensitive drum, and controller for controlling the galvanomirrors in order to set the radiating positions of the laser beams on the photosensitive drum in response to a signal output from the sensor.

Abstract: The image forming apparatus can retain a stable and high image quality for many hours without use of any high precise mechanical parts and without causing any non-uniformity and mal-registration in a color image. In the image forming apparatus, an image recording medium (photosensitive drum) (6a) is driven by a rotative driving mechanism (pulleys and belts) (40a); and an image recording section (print bar) (6c) records an image repeatedly on the rotating image recording medium (6a) in a direction perpendicular to a rotational direction of the image recording medium. The image recorded on the image recording medium (6a) is transcribed onto an image transcribing medium (paper) (22) being fed in the rotational direction of the image recording medium (6a) to form an image.
